Precision agriculture is crucial for increasing food output without expanding the cultivable area, which requires sensors to be deployed for controlling the level of nutrients in the soil. In this paper, we report on a microfluidic electronic tongue (e-tongue) based on impedance measurements which is capable of distinguishing soil samples enriched with plant macronutrients. The e-tongue setup consisted of an array of sensing units made with layer-by-layer films deposited onto gold interdigitated electrodes. Significantly, the sensing units could be reused with adequate reproducibility after a simple washing procedure, thus indicating that there is no cross-contamination in three independent sets of measurements. A high performance was achieved by treating the capacitance data with the multidimensional projection techniques Principal Component Analysis (PCA), Interactive Document Map (IDMAP), and Sammon’s Mapping. While an optimized performance was demonstrated with IDMAP and feature selection, during which data of a limited frequency range were used, the distinction of all soil samples was also possible with the well-established PCA analysis for measurements at a single frequency. The successful use of a simple microfluidic e-tongue for soil analysis paves the way for enhanced tools to support precision agriculture. Full article

The influence of the experimental conditions (glutathione concentration and incubation time and temperature) concerning the covalent immobilization of glutathione via carbodiimide coupling on the behavior of a glutathione modified screen-printed carbon electrode obtained by electrografting is evaluated. The optimized parameters fasten the modification process and improve the performance of the sensor as compared to the usual procedure. This suggests the convenience of a tailored preparation of metal sensors based on metal-binding biomolecules such as glutathione. Full article

In this study, a novel three-component hydrogel has been designed and fabricated via hierarchical self-assembly by amino acid derivative (NPPD), riboflavin (RF) and α-cyclodextrin (α-CD). These molecules were aggregated to form some fibrous structures based on hydrogen bond and π–π stacking. The results show that the hydrogel has a specific response to α-amylase and the fluorescence disappears once hydrolyzed. Therefore, this multi-component hydrogel has potential application in the field of drug delivery. Full article

Tentative title: Microfluidic e-tongue applied in soil analysis
Authors: Toni Riul
Short Abstract: The increasing worldwide population and the same cultivable area demands better use of agricultural practices and natural resources, implying high demand for sensors in precision agriculture. Here we present a microfluidic electronic tongue device as a complementary tool for soil analysis. A control soil sample and aliquots of it enriched with K, Ca, Mg, N, P and S were analysed using impedance measurements from 1Hz – 1MHz. Principal Component Analysis (PCA) and Interactive Document Map (IDMAP) projection technique were explored in data analysis, indicating good reproducibility without evidences of cross-contamination of the microfluidic sensor in three independent sets of measurements.

Title: Recent advances in Magnesium detection: from single selective sensors to multisensory approach
Authors: Larisa Lvova1,3, Corrado Di Natale2,3, Andrey Legin3,4 and Roberto Paolesse1,3
Abstract: In this paper the recent achievements in development of chemical sensors for magnesium ions analysis are oreviewed. The working principles and the main types of sensors applied are described. Focus is placed on the optical sensors and multisensory systems applications for magnesium assessment in different media. Further, a critical outlook on the employment of multisensory approach in comparison to single selective sensors application in biological samples in particular is presented.
